Excel Import POI OLE2 error: Invalid header signature; read 0x74, expected 0xE1

Hi,

I'm attempting to read folder full of xlsm files. However, 2 of the 21 XLSM files I'm trying to read present messages like this:

Invalid header signature; read 0x74776572646E610E, expected 0xE11AB1A1E011CFD0 - Your file appears not to be a valid OLE2 document

Clearly there is something not right about the file headers. I have tried re-saving the files, and saving as xlsb and re-saving as xlsm without success. Any thoughts as to what I can do to correct this behavior? I can think about stripping out the vba content and saving these as xlsx files but I feel like this shouldn't be necessary.

I've read a stack overflow post here which suggests that adding some specific Jar files to my Java path might a way to resolve this.

However on that note I worry about my Java path not being set up right. I have this message when loading PDI:

I think that this is my java path info:

Microsoft Windows [Version 6.3.9600]

C:\WINDOWS\system32>for %i in (java.exe) do @echo. %~$PATH:i

This is what I currently have set for java path in my spoon.bat file:



REM Special console/debug options when called from SpoonConsole.bat or SpoonDebug.bat
if "%SPOON_CONSOLE%"=="1" set PENTAHO_JAVA=C:\Program Files\Java\jre1.8.0_112\bin\java.exe
if not "%SPOON_CONSOLE%"=="1" set PENTAHO_JAVA=C:\Program Files\Java\jre1.8.0_112\bin\javaw.exe
set IS64BITJAVA=0


call "%~dp0set-pentaho-env.bat"
